Characterization of synthetic protocells. (a) Microscopic photograph of hydrogel dispersing in PFOB. (b) Microscopic photograph of the synthetic protocells. (c) The particle size distribution of the synthetic protocells. (d) Atomic force microscopy image of the collapsed synthetic protocell. Scale bar, 10 μm. e-h. Flow cytometry data for synthetic protocells with no fluorescence labeling (e), Cy5.5 labeled lipids (f), FITC labeled hydrogel (g), Cy5.5 labeled lipids and FITC labeled hydrogel (h). i. Confocal images of synthetic protocells. M reflects the membrane, C reflects the core, R1 and R2 are representative synthetic protocells. Scale bar, 100 μm. j. Confocal images of a synthetic protocell. Graphs at the bottom show corresponding line profiles of fluorescence intensities across the synthetic protocell. Scale bar, 10 μm. k. 3D confocal fluorescence reconstructions of a synthetic protocell. Scale bar, 10 μm. l. 3D confocal fluorescence reconstructions of a dried synthetic protocell. Scale bar, 10 μm
